Thefobjelct ofthev invention'is to provide mechanical means yforrnaintaining the proper relation vbetweenthe traveling'note #sheet andlthe tracker barbr yother'coperlinvention `to provide positively;actuated vmeans for restoring the' notesheet ltoits vnormal position, i.le., itsgtrue cour`se,rwhen it has been diverted therefrom; to provide ashifting, device for so, adjusting the sheet which shall' 'be controlled.by the lateral movement ofthe s'heet,itself;fand further, tol y providesuch a kdevice which shall be simple j its construction:andf-operationf'and not w liable to be broken or sodisarranged yas `toY render the samefiinoperative.

In the. form of the deviceA herershown .a

pneumatic operatingrmechanism is emp-loyed -V which comprises acasing 21having flexible side and bottom wal1s,zas indicated at 22 and 23, andprovided .witha diaphragmormov-- able partition 24'l dividing theinterior. of the casing into twocoinpartments orA chambers V25 and 26.vThis diaphragm ormovable partition is `operatively connected tothe leverY 19, and, in thepresent instance, hasfan upwardly .extending arm 27rigidly, secured thereto and connected with thelever 419 by a rod 28.'

' `Each chamber 2fand 26 has a conduithor tube 29 cemmunicatingtherewithand connecting the same with a passage 30 formed `in the base 31 uponwhich the Vopera/ting mechanism is mounted.` AThese passagesBO are, `inturn', connected with asuction pipe 32 which communicates :with asuitable suction apparatus which may be of any suit-f` able character,but is here shown asyasuc- Vtion fanv34f The conduits 29v communicatewith `the passages 30 through valve cham- Y. bers 35v having flat topand bottomjwalls.

The bottom wall of each valve chamber has therein a port 36Vcommunicating with the corresponding passage `30 and the top wall offthe chamberhasfone `or vmore ports'37 connecting the valve chamber withthe atmosphere. A fiat disk-like valve 38 is arranged withineach vvalvechamber 35 and normally restsupon the lower wall thereof and closes theport 36. The suction in the passages30 serves to retain the valve-mem-Vbers 38.1tirmly upon their seats and efectu-4 ally close communicationbetween the suction pipe and the chambers 25 and 26.'

W'ith the valve members in this positionthe chambers are. in opencommunication with the4 atmosphere through the conduits 29 and ports?.The valve members 38 are actuated by electro-magnets,which, in thepresent instance, comprisesolenoids 39, to the coresv of which aresecured the valve stems `40 of the valve members 38. The solenoids 39are'connected in separate circuits 4l and 42respectively, and each ofthesecircuits has a circuit breakerand closer which is notesheet.

sheet 5 is a movable guide 43, which, in the present instance,constitutes one member of a circuit breaker and closer. `This movablememberis preferably formed of thin resili`v ent metal and bears gentlyagainst the adjacent edge o the note sheet Vwhenthe lat- Vtenis initsnormal' position, are., when it is traveling in its proper coursewith .relation f to the .tracker bar 4.. #This 'pressureof' the contactmembers `43 against the opposite"V 'edges of the note-sheet would serveto a cer- V tain extent to counteract any Vtendency on the part ofthenote-sheetto depart from its properccursej,v Any appreciable diversion Yof thelnote-sheet fromV its true course will,

however, move the contact meinber43on` thatlside towardfwhich thenote-sheet is diverted into engagement withthe fixedconi tact member 44of' the ,circuit breaker and closer. These `circuit breakers and closersmaybe of any suitable construction and mayV be'supported from Vthe framel in any suit! able manner, but lhave here shown the fixed' Contact.member 44 as mounted on one of r the iside members of thefframeV 1 fromwhence iteXtends inwardly to a point not far Vremoved from the edge'ofthewnote sheetl and is then bent rearwardly, as shown at 45, and hasrigidly Vsecured to the rear end thereof the movable contact member 43,i

the tivo members being insulated Von'e'from .the other, vas shown at 46.,The circuit breakersand closers maybe located at, any suitable pointsalong the edges of the note-` sheet where they` will be actuated by thelateral displacement of thenote-sheet, but, in

asmuch'as thenote-sheet is tobe maintained in a predetermined relationto the tracker bar, it is rusually desirable'to mount the circuitbreakers and closers as near the tracker "I L bar as is convenient and Ihave, inthe present instanc.e,shown ,the circuit breakers and closers somounted. L n
